Wiffle Fart 

a wet fart......usually sounding like you just did a crap in your pants. Usually caused by a sweating butt and a fart.

I'm having so much fun at the water park....what was that sound? Did you just do a wiffle fart?

Waffle Fart 

A waffle fart is something you call someone who is square (boring) and you don't want around you.

I don't want him to come, he's a waffle fart.

Fart Waffle 

Similar to "sharting"

When passing gas a secretive, more solid waste form is also released... creating a shit-fart aka Fart Waffle.
The Fart Waffle can only happen when wearing underwear, as pressure is needed to create the perfect shape of excrement.

"I must use the facilities before I fart waffle..."

"You should have seen that fart waffle..."

"Welp, I've created a fart waffle."

"Wha... is that a fart waffle?"
